Automatic loading and unloading drilling rod device of soft coal seam gas driller and using method thereof

Abstract

The invention discloses an automatic loading and unloading drilling rod device of a soft coal seam gas driller and a using method thereof. The automatic loading and unloading drilling rod device comprises a spiral drilling rod, a front power head and a rear power head of the drilling rod, a speed measurement device, feeding devices and a rack. Hydraulic jacking columns are arranged around the rack. The feeding devices are arranged in the middle of the upper surface of the rack and each comprises a guide rail and a feeding hydraulic cylinder. A hydraulic power source device is arranged on the side rear portion of the rack and comprises a motor pump set and an oil tank. A track traveling device is arranged at the bottom of the rack. An auxiliary clamping and locating device is fixed between the front power head and the rear power head. Automatic connecting of a next spiral drilling rod with no need of stopping drilling is achieved, so that the situation that coal powder is stacked and an accident of locking (clamping) of the drilling rod is caused due to the need of stopping drilling when the drilling rods are connected by manpower is avoided.

Description

technical field [0001] The invention relates to an automatic loading and unloading drill pipe device for a soft coal seam gas drilling rig and a use method thereof, belonging to the field of mining machinery. Background technique [0002] At present, gas drilling rigs in soft coal seams have always been a research hotspot in the field of mining machinery in my country. During the drilling process of many domestic drilling rigs, when the next auger drill pipe is connected, the long drill pipe that has been drilled into the coal seam needs to stop rotating, resulting in the drilling. The drill pipe part of the coal seam is frequently started and stopped, and the coal slag in the coal hole cannot be discharged continuously, resulting in the accumulation of coal powder inside the drill hole. The rod is locked and cannot be started. In severe cases, the drill rod will break, the drill rod will be lost, and the drill hole will not be able to be used. Such safety accidents will bring...

[0002] At present, gas drilling rigs in soft coal seams have always been a research hotspot in the field of mining machinery in my country. During the drilling process of many domestic drilling rigs, when the next auger drill pipe is connected, the long drill pipe that has been drilled into the coal seam needs to stop rotating, resulting in the drilling. The drill pipe part of the coal seam is frequently started and stopped, and the coal slag in the coal hole cannot be discharged continuously, resulting in the accumulation of coal powder inside the drill hole. The rod is locked and cannot be started. In severe cases, the drill rod will break, the drill rod will be lost, and the drill hole will not be able to be used and other safety accidents, resulting in huge economic losses.
